Hi PVN - a very WARM WELCOME to MASA! Very glad that you found us, and joined MASA!

A VERY basic marine tank setup, would consist of the following (when you read "basic" you will read FISH ONLY as well - and perhaps some VERY hardy corals):
- T8 fluorescent globes (as many as you can fit over the tank's top)
- sump or alternatively, hang-on SKIMMER, ie the ReefOctopus HN-100 (I think)
- skimmer
- DSB (Deep Sand Bed - sand bed where the sand particles sizes are between 0.05mm and 1mm in size, and the sand bed is at least 120mm to 150mm deep)
- live rock - at least 20 to 30% of the tank volume consisting of live rock/bio-rock combination
- TEST-KITS (ammonia, nitrites, nitrates, pH, salinity/SG)
- PATIENCE PATIENCE PATIENCE - ONLY BAD things happen quickly in marines
- READING READING READING - you need to KNOW what the nitrogen cycle is, and how ammonia gets broken down to nitrates
- KNOW that it will take AT LEAST 6 to 8 weeks (minimum) before you can start adding life stock in to the tank (where the tank is "running" on salt water and live rock only)

Welcome to MASA PVN, Jacques covered most of it, all I can say again is read read and read more - ask a lot of questions. This is the only way to learn. Most of all, don't take short cuts, be patient and enjoy this wonderful hobby

Some tips for newbies:1.Evaporation top-ups are done with RO water only, not saltwater2.Please don't keep tangs in a nano - they need lots of swimming space3.Anemones need mature tanks to thrive and clown fish don't need anemones to survive4. "Dilution is the solution to polution" - Anthony Calfo
